His probable grandfather Hillebrand or Gilbert Affleck was born in Scotland and was a burgess in Turku and inspector of gunpowder factories.

Affleck is said to have been a ruthless collector of taxes with little pity towards the poor Finnish peasants. This, and the large and ferocious dog he kept as a pet, earned him the nickname Simo Hurtta (hurtta is Finnish for hound).

Affleck died in 1725 after the Greater Wrath. He is said to have shot himself in the head in his mansion to deny the Finnish peasants raiding his mansion the satisfaction of killing him.
